sounds like ingrown hairs.... does the person you slept with have herpes?? if so, i would be worried, but if you're just assuming that these bumps are herpes then thats totally different. if they have hairs growing out of them, then i dont think its anything to get too worried about. let all the hair grow back and see if they go away... and DONT SHAVE! if they come back, then get them checked out. if they go away and stay away, then they're most likely from shaving.
